* feat(ssh): pre-populate vault password in auth prompts for MFA use cases
When a keyboard-interactive password prompt is shown and the response
field is empty, load and pre-fill the saved vault password. This lets
users with hardware tokens (e.g. YubiKey) press their token to append
a TOTP to the pre-filled base password without re-typing it.
Also pre-fill the prompt-password modal with the vault password so the
same workflow applies when SSH password auth is used with MFA.
